In this paper/poster we study the internal color properties
of a morphologically selected sample of spheroidal galaxies
taken from the Hubble Space Telescope (HST) Advanced Camera
for Surveys (ACS) ERO program of UGC 10214. We take
advantage of the unprecedented ability of ACS deep images to
resolve galaxies at faint limits in order to analyze the
internal color properties of spheroids at pixel-scales. We
use the B475W, V606W and I814W --band
multicolor information to construct V-I and B-V color
maps and extract color gradients for spheroids at I814W
< 24 mag. We asses the ability of ACS to study galaxies at
pixel-scale by comparing it with the results from similar
analysis on the the best multicolor data available for this
purpose from the Hubble Deep Fields (HDFs) North and South.
We find that ACS data requires ~10 times less exposure
time to obtain 1/2 the amount of data obtained previously
with HST. We find a similar fraction of early-type systems
(~0%) with inverse color gradients and blue centers
as well as perturbed color maps comparable to those reported
in the HDFs. We discuss the implication of this in the
context of spheroidal formation.

ACS was developed under NASA contract NAS 5-32864, and this
research is supported by NASA grant NAG5-7697.
